Patent EP-0319980-A2 (EP)
Inventor: HIROSE SYUN-ICHI
IPC: H02J5/00
Filed: 1988-12-08
Abstract: In an apparatus for controlling a power converter, which is adapted to control, in accordance with the PWM system, a voltage-type inverter for system interconnection interposed between the d.c. power source and the a.c. system to interchange power therebetween, a scheme is employed to switch voltage amplitude adjustment signals of respective phases for determining the amplitudes of respective phase output voltages of the inverter depending upon an output voltage phase signal for determining the phase of the output a.c. voltage to thereby provide a phase voltage amplitude, to therefore determine energization periods of respective controllable rectifier elements of the power converter on the basis of the phase voltage amplitude and the output voltage phase signal. Employment of such a scheme makes it possible to independently control the output voltage of the inverter every phase or with respect to both positive and negative sides of the phases, respectively.

Abstract: The collector area of a lateral PNP transistor may be incrementally increased during an electric testing step on wafer of an integrated circuit by purposely forming an auxiliary p-type diffused collector region having fractional dimensions near the primary collector region of the transistor and by permanently shortcircuiting the two regions by means of a "Zener zapping" technique,e.g. by forcing a current through the inversely biased base-collec­tor junction utilizing a suitable contact pad connected to said auxiliary collector region to create localized power dis­sipation conditions sufficient to melt the metal of the respective metals at the adjacent contacts and to form a permanent connection between the two metals. The technique is very useful for adjusting the value of the output cur­rent(s) in precision current generating circuits.

Abstract: Known casings for foundation parts for spread foundations are of channel-shaped design with constant spacing of the side walls, although it is already known that foundation parts of this type can perfectly well be narrower at their top side than at their bottom side. However, since the labour cost of a casing of this type with a narrowing cross-section is relatively high, the foundation parts, in practice, have hitherto been produced with a constant cross-section even with the known casing and the additional concrete requirement has been accepted. It is therefore proposed to use a lattice (5) consolidated with plastic film (6) for the novel casing (l, 11). Due to the flexibility of this material, the labour required for a casing of a foundation part with reduced cross-section can be decidedly reduced. <IMAGE>

Abstract: In such core insertions, the upper and lower core structure (3, 4) carries a multiplicity of centring pins (10), which project with their free ends into recesses of a fuel element end section. Particularly in the case of the upper core structure, the nuts for fixing the centring pins have difficult access in the case of later exchange. The aim is therefore to specify core insertions which manage without securing the nuts to the centring pins. For this purpose, a centring pin (10) is provided with a central through bore (22). The central bore (22) is constructed at its end averted from the fuel elements as a conically tapering stepped bore (23). The stepped bore has a plug, which can be displaced in the axial direction relative to the centring pin and whose lateral surface is constructed conically in the same direction and with the same slope as the stepped bore. A centring pin fits the bore (18) without play. The lateral surface of the centring pin is provided at the level of the stepped bore with a set of grooves (25), which fits the wall of the bore (18) positively once the relative movement of the plug has been concluded.

IPC: E04B1/58
Filed: 1989-12-13
Abstract: The invention relates to an intermediary element for steel elements which have to be fastened to reinforced concrete elements at precisely predetermined points. Since the reinforcement of the reinforced concrete elements prevents holes from being made at any desired point and since dowels in reinforced concrete require a greater distance from fastening means than is customary in steel-construction screw connections, the intermediary element according to the invention is provided with adjustability in at least two directions. It makes it possible furthermore to be able to retain the steel-construction hole pattern in the steel element. The intermediary element as a bridge structure between steel and reinforced concrete is designed in such a way that it separates the internal forces into tensile and compressive forces and assigns the tensile forces only to the dowel. Owing to the structural design of the intermediary element, the dowel stress is minimised. <IMAGE>
